Sapphire is the main character in Below Temperature and a fire mage. She is voiced by the creator of the audio drama. After her father Claw's death, she took on the responsibility of being pack leader. She was taught by the wizard fox Jasper in magic and used it in the great Battle against the snow leopards. Sapphire's self-declared destiny is "to protect the pack, win battles against their greatest enemies, and die in glory." Often called "Sappa" by the twins, she is not the smartest and can sometimes fall into trouble. But her friends are always there to help her, and will support her when she needs it most.
